java - 仅在 jUnit 的情况下获取 java.lang.NoSuchMethodException : io. jsonwebtoken.impl.crypto.MacProvider.generateKey

Question

我最近开始出现以下异常，仅当运行 junit 时。在正常流程中，该方法运行良好。 (事实上​​，即使是 jUnits 以前也能正常工作)

java.lang.NoSuchMethodException: io.jsonwebtoken.impl.crypto.MacProvider.generateKey(io.jsonwebtoken.SignatureAlgorithm)

方法如下:

public static String generateDummyJWT(String userName)
{
    return Jwts.builder().claim("user_name", StringUtils.defaultString(userName)).setAudience("client1").signWith(Keys.secretKeyFor(SignatureAlgorithm.HS384)).compact();   
}

和 jjwt 版本:

以下是完整的堆栈跟踪:

Answer 1

我能够解决我的问题。

团队中的某人在初始化静态最终变量时添加了对上述函数的调用，如下所示:

public static String TOKEN_GUEST = ServiceSpecificUtil.generateDummyJWT(USERNAME);

现在，由于大量使用反射和字节码操作，对 java.security 包的访问通常不能很好地与 PowerMock 配合使用:

虽然我已经提到了this所以发布并尝试了使用建议的解决方案 @PowerMockIgnore 例如:

@PowerMockIgnore({"org.apache.http.conn.ssl.*", "javax.net.ssl.*" , "javax.crypto.*"})

这可能有助于防止从另一个函数调用上述函数时出现错误。但它并不能防止静态变量初始化中的错误。

public static String TOKEN_GUEST = ServiceSpecificUtil.generateDummyJWT(USERNAME);

当我更深入地了解为什么错误仅在静态变量初始化的情况下出现，而不是在从另一个函数调用 ServiceSpecificUtil.generateDummyJWT(USERNAME) 时出现时，我将更新这篇文章。
